Previously, with the continuous foggy weather in many parts of the country, “PM2.5” has become the hottest word in popular science. The main reason for the “explosion” of the PM2.5 value this time is the large emissions of sulfur dioxide, nitrogen oxides and dust caused by coal burning. As one of the current sources of PM2.5 pollution, the exhaust gas emissions of coal-fired boilers are very prominent. 그 중에서 이산화황은 44%, 질소 산화물은 30%를 차지하며 산업용 먼지와 연기 먼지는 26%를 차지합니다. PM2.5의 치료는 주로 산업 탈황 및 탈질입니다. On the one hand, the gas itself will pollute the atmosphere, and on the other hand, the aerosol formed by nitrogen oxides is an important source of PM2.5.

따라서 석탄 화력 보일러의 산소 모니터링은 매우 중요합니다. Using Nernst zirconia oxygen analyzer can effectively monitor the emissions of sulfur dioxide and nitrogen oxides, and play an important role in controlling pollution caused by PM2.5.
